«Finding the organohalogen Freon - 40 near these young, Sun - like stars was surprising,» said Edith Fayolle, a researcher with the Harvard - Smithsonian Center for Astrophysics in Cambridge, Massachusetts in the USA, and lead author of the new paper.

This supports the idea that a young planetary system can inherit the chemical composition of its parent star - forming cloud and opens up the possibility that organohalogens could arrive on planets in young systems during planet formation or via comet impacts.

This suggests that astronomers may have had things around the wrong way; rather than indicating the presence of existing life, organohalogens may be an important element in the little - understood chemistry involved in the origin of life.

Production of organohalogens by microorganisms has to be taken into account for the study of halogen cycling in atmospheric chemistry as well.

Although specific microbial halogenation reactions have been recognized for decades and the link between the dehalogenation of anthropogenic halogenated contaminants in laboratory cultures and contaminated field sites has been well established, only a few studies specifically looked at pristine ecosystems and the genetic potential for microbial degradation of naturally occurring organohalogens, Kappler says.

Assumptions that halogens are inert and that most halogenated organic matter in soils is anthropogenic have been challenged by findings of naturally formed organohalogens.

Mostly it refers to organohalogens — compounds like DDT that incorporate halogens such as chlorine or bromine into organic molecules — that are naturally nearly nonexistent in mammals.

The researchers also note that abundant organohalogens around a young Sun - like analog demonstrates that the organic chemistry present in the interstellar medium involves halogens, which was previously not known.

Kristin Møller Gabrielsen of the Norwegian University of Science and Technology in Trondheim and colleagues report in the journal Environmental Research that they examined the liver, muscle and kidney tissues taken from seven polar bears killed by Inuit hunters in East Greenland in 2011 and analysed the effect of more than 50 contaminants in plasma samples from Ursus maritimus, to see what effect organohalogen compounds could have on the bears» thyroid systems.
